Note A – Summary of Significant Accounting Policies

Nature of Operations : Renasant Corporation (referred to herein as the “Company”) owns and operates Renasant Bank (“Renasant Bank” or the “Bank”) and Renasant Insurance, Inc. The Company offers a diversified range of financial, fiduciary and insurance services to its retail and commercial customers through its subsidiaries and full service offices located throughout north and north central Mississippi, west and middle Tennessee, north and central Alabama and north Georgia.

Basis of Presentation : The accompanying unaudited consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with generally accepted accounting principles for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. For further information regarding the Company’s significant accounting policies, refer to the audited consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011 filed with the Securities and Exchange Commission on March 8, 2012.

Use of Estimates : The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Subsequent Events: The Company has evaluated, for consideration of recognition or disclosure, subsequent events that have occurred through the date of issuance of its financial statements, and has determined that no significant events occurred after March 31, 2012 but prior to the issuance of these financial statements that would have a material impact on its Consolidated Financial Statements.

Impact of Recently-Issued Accounting Standards and Pronouncements : In June 2011, the Financial Accounting Standards Board (“FASB”) issued an update to Accounting Standards Codification Topic (“ASC”) 220, “Comprehensive Income,” (“ASC 220”) that eliminates the option to present components of other comprehensive income as part of the Statements of Changes in Shareholders’ Equity. This update requires that all nonowner changes in shareholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In a single continuous statement, the entity is required to present the components of net income and total net income, the components of other comprehensive income and a total for other comprehensive income, along with the total of comprehensive income in that statement. In the two-statement approach, the first statement should present total net income and its components followed consecutively by a second statement that should present total other comprehensive income, the components of other comprehensive income, and the total of comprehensive income. Regardless of whether an entity chooses to present comprehensive income in a single continuous statement or in two separate but consecutive statements, the entity is required to present on the face of the financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement(s) where the components of net income and the components of other comprehensive income are presented. In December 2011, FASB issued an update to defer the effective date for those changes related to the presentation of reclassifications of items out of accumulated other comprehensive income. While FASB continues to redeliberate whether the reclassification adjustments should be presented on the face of the financial statements, reclassifications out of accumulated other comprehensive income should be reported in accordance with presentation requirements in effect prior to FASB’s update. These updates to ASC 220 became effective for the Company on January 1, 2012. Please refer to the Consolidated Statements of Comprehensive Income and Note J, “Other Comprehensive Income,” in these Notes to Consolidated Financial Statements for disclosures reflecting the Company’s adoption of these updates.

Acquisition of RBC Bank (USA) Trust Division

On August 31, 2011, the Company acquired the Birmingham, Alabama-based trust department of RBC Bank (USA), which services clients in Alabama and Georgia. Under the terms of the transaction, RBC Bank (USA) transferred its approximately $680,000 in assets under management, comprised of personal and institutional clients with over 200 trust, custodial and escrow accounts, to a wholly-owned subsidiary, and Renasant Bank acquired all of the ownership interests in the subsidiary. In connection with the acquisition, the Company recognized a gain of $570, which is recognized under the line item “Gain on acquisition” in the Consolidated Statements of Income for the year ended December 31, 2011. Acquisition costs related to the transaction of $326 were recognized under the line item “Merger-related expenses” in the Consolidated Statements of Income for the year ended December 31, 2011.

Note B – Mergers and Acquisitions (continued)

FDIC-Assisted Acquisitions

On February 4, 2011, the Bank entered into a purchase and assumption agreement with loss-share agreements with the Federal Deposit Insurance Corporation (the “FDIC”) to acquire specified assets and assume specified liabilities of American Trust Bank, a Georgia-chartered bank headquartered in Roswell, Georgia (“American Trust”). American Trust operated 3 branches in the northwest region of Georgia.

In connection with the acquisition, the Bank entered into loss-share agreements with the FDIC that covered $73,657 of American Trust loans (the “covered ATB loans”). The Bank will share in the losses on the asset pools (including single family residential mortgage loans and commercial loans) covered under the loss-share agreements. Pursuant to the terms of the loss-share agreements, the FDIC is obligated to reimburse the Bank for 80% of all eligible losses with respect to covered ATB loans, beginning with the first dollar of loss incurred. The Bank has a corresponding obligation to reimburse the FDIC for 80% of eligible recoveries with respect to covered ATB loans.

The acquisition of American Trust resulted in a pre-tax gain of $8,774. Due to the difference in tax bases of the assets acquired and liabilities assumed, the Company recorded a deferred tax liability of $3,356, resulting in an after-tax gain of $5,418. Under the Internal Revenue Code, the gain will be recognized over the next six years. The foregoing pre-tax and after-tax gains are considered a bargain purchase gain under ASC 805, “Business Combinations,” since the total acquisition-date fair value of the identifiable net assets acquired exceeded the fair value of the consideration transferred. This gain was recognized as noninterest income in the Consolidated Statements of Income.

Acquisition costs related to the American Trust acquisition of $1,325 were recognized under the line item “Merger-related expenses” in the Consolidated Statements of Income for the three months ended March 31, 2011.

The following table sets forth the fair values of the assets acquired and liabilities assumed by the Bank in the acquisition of American Trust as of February 4, 2011:

Note B – Mergers and Acquisitions (continued)

On July 23, 2010, the Bank acquired specified assets and assumed specified liabilities of Crescent Bank & Trust Company, a Georgia-chartered bank headquartered in Jasper, Georgia (“Crescent”), from the FDIC, as receiver for Crescent. Crescent operated 11 branches in the northwest region of Georgia. The acquisition allowed the Company to expand its footprint into new markets in the State of Georgia. In addition, this acquisition gave the Company options to evaluate expansion opportunities in north Georgia and adjacent states.

In connection with the acquisition, the Bank entered into loss-share agreements with the FDIC that covered $361,472 of Crescent loans and $50,168 of other real estate owned (the “covered Crescent assets”). The Bank will share in the losses on the asset pools (including single family residential mortgage loans and commercial loans) covered under the loss-share agreements. Pursuant to the terms of the loss-share agreements, the FDIC is obligated to reimburse the Bank for 80% of all eligible losses with respect to covered Crescent assets, beginning with the first dollar of loss incurred. The Bank has a corresponding obligation to reimburse the FDIC for 80% of eligible recoveries with respect to covered Crescent assets.

Loans acquired in business combinations with evidence of credit deterioration since origination and for which it is probable that all contractually required payments will not be collected are considered to be credit impaired. Acquired credit-impaired loans are accounted for under the accounting guidance for loans and debt securities acquired with deteriorated credit quality, in accordance with ASC 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality” (“ASC 310-30”), and initially measured at fair value, which includes estimated future credit losses expected to be incurred over the life of the loans. Increases in expected cash flows to be collected on these loans are recognized as an adjustment of the loan’s yield over its remaining life, while decreases in expected cash flows are recognized as an impairment. Loans acquired through business combinations that do not meet the specific criteria of ASC 310-30, but for which a discount is attributable, at least in part, to credit quality, are also accounted for under this guidance. As a result, related discounts are recognized subsequently through accretion based on the expected cash flow of the acquired loans.

Acquired loans covered under loss-share agreements with the FDIC are recorded, as of their respective acquisition dates, at fair value. The fair value of these loans represents the expected discounted cash flows to be received over the lives of the loans, taking into account the Company’s estimate of future credit losses on the loans. These loans are excluded from the calculation of the allowance for loan losses because the fair value measurement incorporates an estimate of losses on acquired loans. The Company monitors future cash flows on these loans; to the extent future cash flows deteriorate below initial projections, the Company reserves for these loans in the allowance for loan losses through the provision for loan losses. With respect to the loans covered under loss-share agreements acquired in the Crescent and American Trust transactions, no provision for loan losses was recorded during the three months ended March 31, 2012 or 2011.

In these Notes to Consolidated Financial Statements, the Company refers to loans subject to the loss-share agreements as “covered loans” or “loans covered under loss-share agreements” and loans that are not subject to the loss-share agreements as “not covered loans” or “loans not covered by loss-share agreements.”

As part of the loan portfolio and other real estate owned fair value estimation in connection with FDIC-assisted acquisitions, a FDIC loss-share indemnification asset is established, which represents the present value of the estimated losses on covered assets to be reimbursed by the FDIC. The estimated losses are based on the same cash flow estimates used in determining the fair value of the covered assets. The FDIC loss-share indemnification asset is reduced as losses are recognized on covered assets and loss-share payments are received from the FDIC. Realized losses in excess of estimates as of the date of the acquisition increase the FDIC loss-share indemnification asset. Conversely, when realized losses are less than these estimates, the portion of the FDIC loss-share indemnification asset no longer expected to result in a payment from the FDIC is amortized into interest income using the effective interest method.

Changes in the FDIC loss-share indemnification asset were as follows:

The amortized cost and fair value of securities held to maturity were as follows:

In light of the ongoing fiscal uncertainty in state and local governments, the Company analyzes its exposure to potential losses in its security portfolio on at least a quarterly basis. Management reviews the underlying credit rating and analyzes the financial condition of the respective issuers. Based on this analysis, the Company sold certain securities representing obligations of state and political subdivisions that were classified as held to maturity during 2011. The securities sold showed significant credit deterioration in that an analysis of the financial condition of the respective issuers showed the issuers were operating at net deficits with little to no financial cushion to offset future contingencies. These securities had a carrying value of $5,029, and the Company recognized a net gain of $12 on the sale during the three months ended March 31, 2011. No securities classified as held to maturity were sold during the three months ended March 31, 2012.

The amortized cost and fair value of securities available for sale were as follows:

At March 31, 2012 and December 31, 2011, securities with a carrying value of approximately $391,103 and $305,746, respectively, were pledged to secure government, public and trust deposits. Securities with a carrying value of $9,152 and $20,206 were pledged as collateral for short-term borrowings at March 31, 2012 and December 31, 2011, respectively.

The amortized cost and fair value of securities at March 31, 2012 by contractual maturity are shown below. Expected maturities will differ from contractual maturities because issuers may call or prepay obligations with or without call or prepayment penalties.
